Several factors can affect the speed and performance of an electric scooter:

· Rider weight: A higher rider weight may affect the scooter's maximum speed.
· Terrain and slopes: Riding on hilly or uneven terrain may reduce performance compared to a flat road.
· Battery charge: A low battery may cause the scooter to limit speed or power to save energy.

Settings or riding mode: Check if your scooter is in a specific mode (e.g. Eco mode) that limits maximum speed and power. Switching to Sport mode or a more powerful setting may help.

If your scooter is still under warranty and you suspect a defect, we can arrange for further inspection and, if necessary, a replacement.

There can be a number of reasons why your brakes are not working properly. Here are some common reasons and possible solutions:

· Brake failure or brake retardation:
Loose or worn brake cables can affect brake performance. Please check that the brake cables are properly adjusted and tightened.
Worn or damaged brake pads can also be the cause. In this case, they should be replaced.

· Loud brake noises:
Dirt or deposits on the brake pads or brake discs can cause noises. A thorough cleaning helps ensure smooth operation.
If the brake pads are badly worn or damaged, they should be replaced to eliminate the noise.

· Damaged brake pads or brake discs:
If you find obvious damage to the brake pads or brake discs, such as deformation or severe wear, they need to be replaced.
Please check your brake system for any of the above problems. If you are not sure, please send us a video or picture of your brake system so that we can help you further.

If the problem persists or cannot be solved by yourself, please let us know. We will take the necessary measures to repair or replace the defective part.

After starting the electric vehicle, long press the "M" button to turn on the headlights.
